The above type is KM#302.1 and the known date range (according to KM) is AH1071/Ry.3 to AH1078/Ry.10
The next issue is listed in KM as #300.20 with a known date range from AH1083/16 to AH1118/Ry.5
Your coin is identical to the coin on ZENO
#47537. It is, I think, the most rare type of this mint. The couplet reads (from bottom to top):
(obv.)
shah aurangzeb alamgir /
(rev.)
zad dar jahan chu badr munir. Below:
zarb bhakkar. The mint usually doesn’t form a part of the couplet.
BTW you need to swap the images of obv. and rev.
As for as prices, KM is not a trustworthy guide either. I obtained my first coin of this mint AH1091/Ry.24 (KM#300.20; ZENO
#30647) in March 1996 and
AH1072/Ry.4 (KM#302.1; ZENO
#30646) in Oct. 1996 both for £ 20 each, from Spinks.
The coin similar to yours AH1078/Ry.10 (KM#303.1; ZENO
#47537) I obtained in Sept. 2007 from Indus Coins for £ 75. Just to give an idea.
